U.S. stocks fell more than 1% Wednesday after the Fed said it was cutting another $10 billion per month from its economic stimulus program. Investors were disappointed the central bank didn't address the recent turmoil in emerging markets.

The turmoil has prompted a flight from riskier assets, including stocks.

The Dow Jones industrial average has fallen on six out of the last seven trading days and is down 5% so far this year. The S&P 500 index has dropped by 4% since the start of 2014, with the bulk of the losses sustained over the past few days.

Investors will get their first reading of U.S. fourth-quarter GDP from the Commerce Department Thursday at 8:30 a.m. ET. Briefing.com's consensus forecast is calling for annual growth of 3% for the broadest measure of the economy.

Also at 8:30, the government will release its weekly report on initial jobless claims.

Beyond economic data, it's another day chock full of earnings reports.

"Today is one of the busiest days on the corporate reporting calendar with 10% of the S&P 500 provid[ing] earnings updates, including Exxon Mobile and Google which are the second and third largest companies by market cap," Deutsche Bank analyst Jim Reid wrote in a market note.

UPS(UPS) and Exxon Mobil(XOM) are on deck to report ahead of the opening bell, while. Amazon(AMZN) and Google(GOOG) are set to report in the afternoon.
